Solve the equation ​

Mathematics
1 answer:
Lina20 [59]3 years ago
7 0

Answer:

b = 6

Step-by-step explanation:

Step 1: Write equation

-2.6b + 4 = 0.9b - 17

Step 2: Solve for <em>b</em>

<u>Add 2.6b on both sides:</u> 4 = 3.5b - 17

<u>Add 17 on both sides:</u> 21 = 3.5b

<u>Divide both sides by 3.5:</u> b = 6

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

-2.6(6) + 4 = 0.9(6) - 17

-15.6 + 4 = 5.4 - 17

-11.6 = -11.6

Reasoning: Alternate interior angle theorem

The angles shown are inside the parallel lines, so they are interior angles. They are also considered alternate angles because they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this.

The length of a rectangle is 59 inches greater than twice the width. If the diagonal is 2 inches more than the​ length, find the
Paul [167]
So.. hmm notice the picture here

we know the length is 59 more than twice the width,
twice the width, 2 * w, or 2w
59 more than that
2w + 59

we also know that, whatever that is, the diagonal of it is,
2 more inches than that, or
(2w + 59) + 2

now.. use the pythagorean theorem
\bf c^2=a^2+b^2\implies \qquad &#10;\begin{cases}&#10;a=2w+59\\&#10;b=w\\&#10;c=(2w+59)+2\to 2w+61&#10;\end{cases}&#10;\\\\\\&#10;(2w+61)^2=(2w+59)^2+(w)^2&#10;\\  \qquad\qquad \uparrow\qquad \qquad\qquad \qquad \uparrow  \\&#10;\textit{expand using binomial theorem, or FOIL}

you'd end up with a quadratic, after simplifying, solve for "w"
